perf/arm: Add missing .suppress_bind_attrs
[ Upstream commit 860a831de1
]
PMU drivers should set .suppress_bind_attrs so that userspace is denied
the opportunity to pull the driver out from underneath an in-use PMU
(with predictably unpleasant consequences). Somehow both the CMN and NI
drivers have managed to miss this; put that right.
